Well build what you are going to want but if you cant get the welds to lay right on that stamped pan, making your own isnt going to be any better. Your going to get the same welds on the new pan.

My advice is to practice on light gauges sheet metal before you go making one from scratch if your having a hard time. Like body work, preparation is very important. Try welding in small amounts, say 1" increments and alternating the welds 180 degrees away from one another.
